Polyketides as the conserved basis for diverse marine toxin biosyntheses. Over the past three decades, the frequency and global distribution of harmful marine biotoxin events appears to have increased, and human poisonings have regularly occurred. This project will develop an understanding of the genetics and physiology of toxin-producing marine microorganisms in response to pollution and climatic change that is critical for the management of these species and for the risk assessment of contamin ....Polyketides as the conserved basis for diverse marine toxin biosyntheses. Over the past three decades, the frequency and global distribution of harmful marine biotoxin events appears to have increased, and human poisonings have regularly occurred. This project will develop an understanding of the genetics and physiology of toxin-producing marine microorganisms in response to pollution and climatic change that is critical for the management of these species and for the risk assessment of contaminated seafood. The direct outcomes of this work constitute an easier, more economical and ethical alternative to current toxicity testing. Further benefits of this research will also be tangible for the environmental, biosecurity, fisheries and pharmaceutical sectors of Australian community and industry.Read moreRead less
The diversity and assembly of optics in nature. Optics, such as the design of new coloured reflectors, is a research strength for Australia. A reason for this is the potential for application - optical devices can be found far and wide in our everyday lives, from security devices on banknotes (holograms), to computer monitors (LCDs). An interesting parallel exists in nature - animals possess similar optical devices to those we use. So it makes sense to examine the animals' devices in a search fo ....The diversity and assembly of optics in nature. Optics, such as the design of new coloured reflectors, is a research strength for Australia. A reason for this is the potential for application - optical devices can be found far and wide in our everyday lives, from security devices on banknotes (holograms), to computer monitors (LCDs). An interesting parallel exists in nature - animals possess similar optical devices to those we use. So it makes sense to examine the animals' devices in a search for new reflectors, and that's an aim of this project. And since reflectors are often difficult to make, why not let animals make reflectors for us? That is a further aim of this project. Soon we may have genetically-altered butterfly scales embedded in our credit cards that cannot be counterfeited.Read moreRead less
Genetic code expansion of a eukaryotic in vitro translation system. The genetic code programs biosynthesis of polypeptides with efficiency vastly superior to chemical engineering. As the chemical diversity of natural amino acids in proteins is limited, finding ways to include “unnatural” amino acids can supercharge biology with a range of new protein activities. While the genetic code can be expanded to make space for unnatural amino acids, the rarity of free codons and reliance on prokaryotic ....Genetic code expansion of a eukaryotic in vitro translation system. The genetic code programs biosynthesis of polypeptides with efficiency vastly superior to chemical engineering. As the chemical diversity of natural amino acids in proteins is limited, finding ways to include “unnatural” amino acids can supercharge biology with a range of new protein activities. While the genetic code can be expanded to make space for unnatural amino acids, the rarity of free codons and reliance on prokaryotic organisms limit the applicability of this approach. We will develop a new higher-organism cell-free protein production system that can incorporate multiple unnatural amino acids into defined points of proteins. This, enabling and broadly applicable technology, will be tested by constructing opioid biosensors.Read moreRead less

The sequencing of the human genome has led to redirection of effort towards the rapid characterisation of the products of genes, proteins. This project will establish state of the art facilities for protein identification and characterisation in the Hunter Region. The investigators are representative of several major research programs and are unified by their specific expertise in the fundamental molecular mechanisms underlying the control of cellular processes in plants, animals and humans. Understanding these mechanisms will provide the basis for improved management of the environment and pathological conditions through identifying molecular targets for diagnosis, genetic manipulation or drug design.Read moreRead less
Molecular mechanisms of cyclic Adenosine Monophosphate (AMP) induced apoptosis. Cyclic Adenosine Monophosphate (cAMP) is an important cellular chemical necessary for cell growth. However, de-regulated cAMP production in response to altered physiology can result in cellular death or apoptosis. This is attributed to the development of certain human diseases and this project aims to understand the molecular mechanism behind this process.
Elucidating the regulation of cell death by random mutagenesis of key apoptotic proteins. All organisms need to remove damaged or excessive cells. This cell death process is called apoptosis. Defects in apoptosis result in numerous diseases including cancer, and neurodegenerative and immune disorders. Determining how this process is regulated is of crucial importance for therapeutic intervention. We will utilise a powerful strategy to mutate proteins required for apoptosis so that they no longer ....Elucidating the regulation of cell death by random mutagenesis of key apoptotic proteins. All organisms need to remove damaged or excessive cells. This cell death process is called apoptosis. Defects in apoptosis result in numerous diseases including cancer, and neurodegenerative and immune disorders. Determining how this process is regulated is of crucial importance for therapeutic intervention. We will utilise a powerful strategy to mutate proteins required for apoptosis so that they no longer work, which will allow the identification of protein regions essential for cell death activity . This will lead to identification of potential drug targets to control apoptosis. Elucidating the mechanism of cell death will lead to the development of novel and improved therapies for diseases such as cancer and neurodegenerative disease.Read moreRead less
Determining the molecular regulation of blood vessel development and angiogenesis. Abnormal blood vessel growth is associated with diseases including cancer, macular degeneration, diabetic retinopathy and chronic inflammation. This project focuses on understanding normal blood vessel growth in order to gather clues to help discover ways of preventing abnormal blood vessel growth during disease.
Investigation of the biology of insulin-like growth factor 1 and its derivatives for the development of new therapeutics. This project will investigate the biology of insulin-like growth factor 1, a key molecule in growth, development and, in particular, the wound healing process. Its success will lead to improved treatments for non-healing (chronic) wounds and, potentially, new anti-cancer treatments.
Molecular control of apoptosis and protein homeostasis. A million cells are produced every second by cell division. At the same time a million cells commit suicide by a process called apoptosis. When cells fail to die when they should they can develop into cancers. In heart attacks, stroke and neurodegenerative diseases, many cells appear to activate their self destruct mechanism to die unnecessarily. Drugs that can cause cancer cells to kill themselves, or drugs that prevent cells dying when th ....Molecular control of apoptosis and protein homeostasis. A million cells are produced every second by cell division. At the same time a million cells commit suicide by a process called apoptosis. When cells fail to die when they should they can develop into cancers. In heart attacks, stroke and neurodegenerative diseases, many cells appear to activate their self destruct mechanism to die unnecessarily. Drugs that can cause cancer cells to kill themselves, or drugs that prevent cells dying when they shouldn't, would make a major impact on many important diseases. Understanding the molecular mechanisms of cell death is the first step towards developing these drugs.Read moreRead less
Determination of the mechanisms of immune system regulation of inflammation by the human protein, chaperonin 10. The aim of this project is to determine the mechanisms by which a human protein, chaperonin 10 (Cpn10), regulates the immune system and suppresses inflammation. When cells of the human immune system are challenged with lipopolysaccharide (LPS) (a product of bacterial infection), the pro-inflammatory cytokine TNF is released. Cpn10 has been shown to suppress production of TNF on chall ....Determination of the mechanisms of immune system regulation of inflammation by the human protein, chaperonin 10. The aim of this project is to determine the mechanisms by which a human protein, chaperonin 10 (Cpn10), regulates the immune system and suppresses inflammation. When cells of the human immune system are challenged with lipopolysaccharide (LPS) (a product of bacterial infection), the pro-inflammatory cytokine TNF is released. Cpn10 has been shown to suppress production of TNF on challenge of cells with LPS, while increasing the levels of the anti-inflammatory cytokine IL-10. Investigating the role of Cpn10 in modulating inflammation will contribute to the understanding and treatment of diseases associated with inflammation, including multiple sclerosis and rheumatoid arthritis.Read moreRead less
